PIP-WATCH ZERO: common questions

What microcontroller does the PIP-WATCH ZERO use?

The PIP-WATCH ZERO is built around the STM32F103RXT, from the STM32 family.

How big is the PIP-WATCH ZERO PCB?

The PIP-WATCH ZERO measures 80 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PIP-WATCH ZERO?

74 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the PIP-WATCH ZERO design files?

From the jsyk/PIP-Watch repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PIP-WATCH ZERO design in my own project?

The repository has no license, so all rights stay with jsyk. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PIP-WATCH ZERO without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
